HT7991 Datasheet (Holtek Semiconductor) - 1MHz Asynchronous Step-up PWM Converter

HT7991, 1MHz Asynchronous Step-up PWM Converter

The HT7991 is a current mode asynchronous stepup DC-DC converter.

The fully integrated power MOSFET transistor, with its 0.2Ω drain source resistance, ensures a high level of device power efficiency.

A fixed 1MHz switching frequency has been chosen to permit smaller inductors to be used in the appli
